PATENTEUAPRZQIHYS SHEET 5 BF 7 N19. 8 ow ROTARY CASH DRAWER MECHANISMFOR CURRENCY DISPENSER BACKGROUND OF THE INVENTION 1. Field of theInvention The invention relates to a currency dispenser actuated by acoded card after card verification. and more particularly to a rotarycash drawer construction having a pocket which receives a requestedamount of currency from a stored currency supply in the dispensermechanism of a remote banking unit and delivers the requested currencyin the drawer pocket to a location readily accessible for removal by therequesting customer. Also. the invention relates to a currency dispensercash drawer construction providing maximum security against attack.having a large delivery pocket providing maximum accessibility when openyet protecting the contents of the open pocket against air currents. andwhich construction may be easily serviced and has minimum possibility ofinjury to the customer user.

2. Description of the Prior Art Prior currency dispensers have a varietyof means for delivering the currency being dispensed to thecustomer-user. Some currency dispensers have sliding or linearly-movabledrawers containing currency dispensed, which drawers are moved to one ormore open positions. In one known movable drawer type, the drawer isdelivered to a partially-open position and then is pulled by thecustomer to a fully-open position to permit the currency therein to beremoved by the customer. Another movable drawer type dispenser has ahinged drawer head which must be moved to a hinged-open position by thecustomer to remove from the drawer the currency being dispensed.

Other prior currency dispensers have delivered or ejected the currencybeing dispensed through a narrow slot. This places limitations upon theamount of currency or the thickness of a packet or sheaf of bills beingdispensed.

Many difficulties and undesirable characteristics are present in theconstruction. operation or use of such prior dispenser cash drawer ordelivery devices, including the requirement that the customer mustmanipulate a drawer or part thereof in use. Also, complications areinvolved in providing security against attack or unauthorized access inorder to meet banking or underwriter requirements. The projection of adrawer from the facia of a banking unit when the drawer is in openposition may result in the projecting drawer being bumped by or injuringa user. Complications may arise in providing a sliding drawer motion foropening and closing the drawer and at the same time in avoiding thepossibility of customer injury by pinching a hand. The possibleretention of undesired objects in the drawer presents a problem, as wellas accessibility of the open drawer to air currents which may blowcurrency from the open drawer. The inability to abort a dispensing cyclein the event of a miscount of currency delivered to the drawer, or achange in the customers request characterizes prior devices. Thelimitation in the size of a packet of currency that may be deliveredthrough a slot also can be a problem. Finally, prior devices involvecomplications in providing means to detect the presence or absence of anobject in the drawer.

countered in the construction. operation or use of prior dispenser cashdelivery devices.

DESCRIPTION OF THE PREFERRED EMBODIMENT In typical automatic bankingunit for dispensing currency in response to the presentation by a bankcustomer of coded card means is indicated at 1. Such currency-dispensingunit I may be energized upon a customer presenting or entering a codedcard into slot 2. Then the coded card is verified to confirm that it isan authorized card and that the user thereof is the authorized user.

After card and customer verification has been carried out, keyboardentries may be made by the customer at 3 in accordance with instructionpresented to the customer at instruction panel 4. The entries amongother matters indicate the amount of currency that the customer desiresto withdraw. As a result of proper keyboard entries. the currency isdischarged from a currency supply to conveyor means which delivers it tothe pocket 38 of the rotary cash drawer generally indicated at 6. Thesupply of currency is held in a protected location within the housing ofbanking unit I.

This currency supply and delivery mechanism is generally indicated bythe block 7 in FIG. I, and is equipped with conveyor means 8 whichdelivers the requested amount of currency to the rotary cash drawer 6.The currency supply and conveyor mechanism 7-8 which delivers currencyto the cash drawer 6 forms no part of the invention but may comprise astandard unit such as shown in Whitehead Et Al US. Pat. No. 3,760,158.

The rotary cash drawer 6 has rotor support frame means including anupper frame member 9, a lower frame member 10, and end frame members 11and 12. Frame members 9 and 10 preferably have flanges 13 and 14 whichare bolted at 15 through flange bolt holes 16 and through a housing wallportion 17 to a frame member 18, L-shaped in cross section (FIG. 2). Thehousing wall 17, upper and lower frame members 9 and 10 and mountingframe member 18 each preferably is made of relatively heavy protectiveplate metal of the required thickness to provide the necessary securityagainst unauthorized access by an intruder to the interior of thehousing of remote unit 1. Thus. the rotary cash drawer assembly 6 islocated within and has security protection by the secure housing of unit1.

The banking unit housing 1 preferably has a recessed facia indicated at19 in FIG. 1, and this facia may be trimmed with a trim member indicatedgenerally at 20. The trim member 20, frame member 18 and housing wall 17jointly are formed with a relatively wide elongated slot having spacedupper and lower edges 21 and 22, and access is gained to the rotary cashdrawer 6 through the slot defined by edges 21 and 22 in a manner to bedescribed.

The rotary cash drawer 6 has a rotor 23. Rotor 23 has a cylindricalouter wall 24 with a cylindrical outer surface 240 and is provided withstub shafts 25 and 26 journaled, respectively, in bearings 27 and 28mounted in the end frame members 11 and 12. Rotor stub shafts 25 and 26project outwardly. axially, respectively. from transverse rotorpartition walls 29 and 30. A recessed annular cavity 31 and 32 is formedin the ends of rotor 23 beyond partition walls 29 and 30, respectively,and surrounding portions of stub shafts 25 and 26, as shown in FIGS. 5and 6. Thus. rotor 23 is rotatable between the spaced upper and lowersupport frame members 9 and 10, as shown in FIGS. 13-15. Lower framemember 10 is cut away behind its flange 14, as indicated at 33 in FIG.13 and in dotted lines in FIG. 3, to leave only fingers 34 projectingrearwardly from either end of the lower frame member 10.

A portion of the rotor 23 as shown in FIGS. 4, 9, 10 and 13-16 projectsforwardly beyond the front surfaces 35 of the flanges 13 and 14 of upperand lower frame members 9 and 10. The projecting rotor portion alsoprojects through the housing slot between the upper and lower slot edges21 and 22 (FIGS. 1 and 2).

A longitudinally-extending arcuate slot 36 is formed in the cylindricalrotor wall 24, and a liner member 37 extending axially of rotor 23,generally U-shaped in transverse cross section, is mounted within thecavity formed by cylindrical rotor wall 24 with the spaced open linerU-edges 37a and 37b aligned with the spaced edges 36a and 36b which formthe arcuate rotor slot 36 (FIGS. 13-15). The aligned rotor slot edges36a and 36b and liner edges 37a and 37b define spaced rotary cash drawerlips which are adapted, when the rotor 23 is in the open" position shownin FIGS. 3, 4, 5 and 13 to be aligned with the spaced housing slot edges21 and 22.

Rotor 23 is rotatably movable between the open" position shown in FIG.13, the home" position shown in FIG. 15, and the *dump" position shownin FIG. 14.

The U-shaped liner 37 thus forms a pocket generally indicated at 38which opens through the opening defined by the arcuate slot 36 and lineredges 37a and 37b. When the rotor 23 is in the open" position of FIG.13. the U-walls of liner 37 preferably extend generally horizontally. asshown; and there is full. easy and free access through the largeropening to the pocket 38.

The opening of pocket 38 is directed inwardly. upwardly within thebanking unit housing when the rotor 23 is in the home" position. shownin FIGS. 2 and 15. When the rotor 23 is in the dump" position of FIG.14, the opening of pocket 38 is directed downwardly within the bankingunit housing above a tray 39 movably mounted within the housing.

The liner 37 is supported within the rotor 23 by angle brackets 40bolted at 41 and 42, respectively, to end portions of the liner 37 androtor partition walls 29 and 30 (FIGS. 6-8).

Rotor 23 preferably is counterbalanced to compensate for the arcuateslot 36 by mounting weights 43 and 44, respectively. in the recessed endcavities 31 and 32 of the rotor (FIGS. 7 and 8). the weights 43-44 beingheld in place by screws 45. A boss 46 is formed integrally of rotorpartition wall 30 (FIG. 8) projecting through the weight 44, and a rotorcontrol stop pin 47 is mounted on boss 46 projecting from the right-handend of rotor 23 (FIGS. 3. 7 and 8) for a purpose to be described.

A pair of sensor sight openings 48 formed in each rotor partition wall29 and 30, and the openings 48 of each pair are located at diametricallyopposite positions (FIGS. 6 and 7). These locations of the openings 48of each pair are disposed vertically one above the other. as shown inFIGS. 6 and 7 when the rotor is in the "open" position. illustrated inFIG. 6.

A series of four prisms 49. 50, 51 and 52 is mounted on the exterior ofthe U-shaped leg walls of liner 37 (FIGS. 6, 13, 14, 15 and 18). Theprisms thus are located in the moon-shaped cavities formed between therotor wall 24 and the leg walls of U-shaped liner member 37.

Each prism preferably is a molded and polished plastic part with amounting flange 53 (FIG. 18) and a prism cylinder 54 having a flat face55, an angled face 56, and an end face 57 arranged at right angles withthe flat face 55 at the underend of the cylinder 54 and formed as a partof the underside of flange 53. Openings 58 are formed in the liner wallsto expose the prism end faces 57 to the interior of the liner pocket 38.The prisms are held in place by mounting bolts 59.

Electric eye bulbs 60a and 60b are mounted. respectively, on the endframe members 11 and 12 outside of openings 61 and 62 formed thereinwhich are aligned with the upper openings 48 (FIG. 6) when the rotor isin open" position; and light sensor photocell switches 63 and 64 arealso mounted, respectively, on frame members 11 and 12 opposite openings65 and 66 in end members 11 and 12. The photocells and openings 63-66are aligned as shown in FIG. 6 with the lower openings 48 in the rotorpartition walls 29 and 30.

Thus. a light beam from the electric eye bulb 60a (FIG. 6) is directedthrough openings 61 and 48 and through the flat face 55 of prism 49, andpart of the beam is reflected from angle face 56 and passes through theend face 57 of prism 49 and is directed downward to the end face 57 ofprism 51 and is partially reflected by the prism angle face 56, andpasses outward from prism flat face 55 toward the Iefi through alignedopenings 48 and 6S striking photocell 63. The

path of such light beam is shown in FIG. 6 by the dotdash line 67.

A similar light beam is projected from electric eye bulb 6011 throughprisms 50 and 52 and the beam strikes photocell 64. The purpose of theselight beams and the electric eye-photocell systems is described below.

Rotor 23 is rotatable in either direction between limits of movementcontrolled by the stop member 68 (FIGS. 3 and 11) having an adjustablestop abutment 69 for the open" position and an adjustable stop abutment70 for the dump" position. Stop member 68 is mounted on the inside faceof the end frame member 12 (FIG. 3). Stop abutment 70 is engaged byrotor control stop pin 47 to limit clockwise rotor movement, viewing theright end of the mechanism (FIG. 4), as shown in FIG. 12 wherein therotor is in dump" position with the slot 36 opening downward.

Stop abutment 69 is engaged by stop pin 47 to limit counterclockwiserotor movement when the rotor is in open" position, as indicated inFIGS. 3 and 10. At this time. the rotor access slot 36 is directed tothe left in FIG. 10 or opens toward the viewer in FIG. 3.

When the rotor 23 is in home" position (FIG. 11), the access slot 36opens upwardly toward the right viewing FIG. 11; and at this time, alock pin 71 is projected through an opening 72 in the upper frame member9 and into an aligned opening 73 in the rotor wall 24 communicating withthe recessed cavity 32. The stop pin 71 is shown engaged in the home"position illustrated in FIG. 11 and is shown disengaged in otherpositions illustrated in FIGS. 3, 6, l and 12. Lock pin 71 is actuatedby a solenoid 74. A rotor movement control printed circuit optical limitswitch plate or panel 75 is mounted by bolts 76 and spacers 77 (FIGS. 6and at the right-hand end of the mechanism (FIG. 6). Panel 75 on itsouter face has an open sensor 78, a home sensor 79, and a dump" sensor80; and these sensors are adapted to have light beams interrupted bymovable fingers mounted on the rotor.

The movable finger means consist of an inner disc 81 with a projectingL-shaped finger 82 and an outer disc 83 with a projecting L-shapedfinger 84. The discs 81 and 83 are relatively adjustable rotatably withrespect to each other and may be clamped in adjusted position by screws85. The assembly of discs 81 and 83 on a hub 86 is adjustably mounted onthe projecting end 87 of stub shaft 26.

Finger 84 of outer disc 83 interrupts light in home" sensor 79 whichacts as a limit switch to control operation of the drive motors for therotor 23, to be described; while finger 82 selectively actuates opensensor 78 (FIG. 10) or dump sensors 80 (FIG. 12) as limit switches tocontrol the drive motors for rotor movement. The printed circuit opticallimit switch panel 75 and its components are of typical construction andpanel 75 is connected by a cable 88 with the circuitry. to be described,for controlling the operation of the rotary cash drawer 6.

A motor mount plate 89 is pivotally mounted at 90 to end frame member11. Plate 89 normally is biased in a counterclockwise direction byspring 91, viewing FIGS. 9 and 16. A drive motor 92 is mounted on alower portion of plate 89 having a drive gear 93 adapted to be moved toa position engaging gear 94, mounted on the stub shaft 25 of rotor 23.The motordrive gear means 92-94 provides a positive drive meansengageable with the rotor 23 to rotate the rotor in one direction,counterclockwise viewing FIG. 12, and clockwise viewing FIGS. 13, I4, 15and 16 from dump" position to home position, and also drives rotor 23from the home to the open" position of FIGS. 9. I0 and 13.

There is a second separate drive motor 95 mounted on an upper portion ofplate 89 having a friction drive wheel 96 adapted to engage theperiphery of the rotor 23 (FIG, 16) when the plate 89 is rotatedclockwise (FIG. 16) by the action of a solenoid 97 connected by alinkage 98 with bracket means 99 mounted on the upper end of motor mountplate 89.

Plate 89 when rotated clockwise, as shown in FIG. 16, disengages thegear drive and engages the friction drive 96 with rotor 23. Thus, whenfriction drive motor 95 is energized, drive wheel 96 rotates rotor 23counterclockwise viewing FIG. 16 from open" position back to dumpposition. This rotor movement is clockwise from the open' position ofFIG. 10 to the dump position of FIG. 12.

Preferably, movement of plate 89 is guided and controlled by the bushingpins 100 extending through slots 101 in the lower end of plate 89.

A segment ratchet wheel 102 is mounted on the outer end of stub shaft25. Ratchet pawl 103 may be moved in a position to engage the ratchetteeth of wheel 102 to prevent clockwise movement of the rotor 23 (FIG.16) as the rotor is being rotated counterclockwise by the friction drivewheel 96 from the open" position to the dump position. Pawl 103 isactivated to ratchet wheel engaging position by push rod 104 connectedat 105 with plate 89. Thus, when plate 89 is moved clockwise (FIG. 16),by solenoid 97 to engage friction drive wheel 96 with rotor 23 and motor95 is energized to to tate rotor 23 in a counterclockwise direction,push rod 104 moves pawl 103 to ratchet engageable position.

When the gear drive 92-94 is engaged and the friction drive 96 isdisengaged (FIG. 9), push rod 104 moves pawl 103 to the position of FIG.9 in which it does not engage ratchet wheel 102. It is necessary toprevent retrograde movement of rotor 23 when it is being moved fromopen" to dump" position by the friction drive, in order to preventanyone from backing up the rotor for any purpose whatsoever duringfriction drive operation to and at dump position. Thus, an unauthorizdperson cannot gain access to or remove material in the rotor pocket thatis intended to be dumped.

On the other hand, the friction drive is necessary to prevent injury tothe hand of an authorized user if trapped in the pocket during rotormovement away from open" position.

A transformer 106, relays 107, etc., may be mounted on a housing 108located on top of the upper frame member 9. Circuitry, cable harnesses,terminal strips, etc., may be located on or within the housing 108 fromwhich circuitry to the motors, solenoids, electric eyes, photocells andcontrol panels may extend for operating the mechanism in accordance witha programmed cycle of movement.

The electric eye 60a and 60b and photocell 63 and 64 systems providebeams of light as described and as illustrated by the dot-dash line 67,when the rotor 23 is in open" position to determine the presence or absence of any object such as paper money in the pocket 38.

In other words, if paper money has been delivered to the pocket 38 inthe "home" position and the rotor 23 moved to open position to renderthe money accessible to a customer, the paper money lying on the lowerleg of liner 37 (viewing FIG. 6) will interrupt either the beam 67 or asimilar beam emanating from electric eye 64. Interrupted light beams mayprovide a control of circuitry in one condition. When the customerremoves the paper money, the beam 67 and the similar one at the right ofFIG. 6 will no longer be interrupted. Thus, energized photocells 63 and64 provide another condition which senses the absence of anything in thepocket. This may be used to inititate a next step in the programmedoperation of the rotor.

CYCLE OF ROTOR OPERATlON IN GENERAL Assume that the rotatable cashdrawer 6 is in a waiting condition with the rotor in home" position. asshown in FIGS. 1, 2, ll and 15. A customer desiring to obtain currencyfrom the automatic banking unit l, presents his coded card in the usualmanner to the slot 2 after which the customer is directed to key invarious information so that the card may be checked and the amountentered as to currency which the customer desires the unit to dispense.

Keying in the amount activates the currency supply and deliverymechanism 7 to deliver the requested amount of money to the conveyor 8which discharges the currency into the open pocket 38 of the rotor 23.The money count, meanwhile, is verified by the delivery mechanism 7.Upon verification, a signal activates the circuitry for the rotary cashdrawer 6 to energize solenoid 74 to retract the lock pin 71 (which isthe deadlock for the rotor in home" position) to retracted position ofFIGS. 6, l and 12.

At the same time, positive gear drive motor 92 is energized to rotaterotor 23 from home position to open" position of FIGS. 6, l0 and 13.When in open position, the electric eye photocell sensor system becomesoperative. The money in the pocket 38 is accessible for removal by thecustomer. When the money has been removed, the sensor light beam systemis re-established, signaling the friction drive motor 95 to be energizedand the solenoid 97 to move plate 89 to engage the friction drive androtate the rotor 23 from "open" position back to "dump" position ofFIGS. 12 and 14. Thus, anything which may have been left in the pocket38, or placed therein by a customer or an unauthorized person, is dumpedfrom the rotor into tray 39.

[n the event that the customer does not remove the currency to bedispensed from the pocket 38 while the rotor 23 is in open positionduring a predetermined period of time, at the end of such lapsed timeperiod, the rotor moves automatically from open" to dump position inorder to dump the currency that was not removed.

After arriving at dump position and dwelling there for the necessarytime to permit completion of the dumping operation, the programming ofthe equipment disengages the friction motor drive and engages the directgear drive of the rotor to move the rotor from dump position to home"position. This completes the cycle and renders the equipment ready forthe next cash dispensing operation.

Situations may arise in which the improved construction provides extrasecurity and safe, accurate and protective operation. Among othermatters, these may be described by two examples.

First, if the count of money supplied from the currency supply anddelivery mechanism 7 is incorrect, the mechansim 7 delivers a signal tointerrupt the programmed operation and directly energize the frictiondrive from motor to rotate rotor 23 from the home position of FIG. 15 tothe dump" position of FIG. l4, thereby dumping the incorrect amount ofmoney that had been delivered to the pocket 38.

Second, if a customer changes his mind regarding the amount of moneybeing requested before the money has been made accessible at the slotbetween edges 2] and 22. the customer may depress a stop button atkeyboard 3 which interrupts further operation of the entire moneydispensing procedure and signals the rotor control to move the rotor todump position.

In either instance, after the rotor 23 has been moved to dump" positionand anything remaining in its pocket 38 discharged to tray 39, thenormal cycle of operation again takes over and moves the rotor back tohome" position, ready for the next cash-dispensing operation.

In each example, the operation of the rotary cash drawer is aborted, andanything in the rotor pocket 38 is dumped. Such capability involves whatwe believe to be a completely new concept in the automaticcurrency-dispensing field.

The dumping concept of the new rotary cash drawer provides furtheradvantages in that the larger and readily-accessible pocket 38 with awide opening permits objects other than currency or paper money to becontained therein, such as sacks of banking media, for example, checks,currency and coin to be deposited. Because of this capability, therotary cash drawer can be used as a depository in which banking mediamay be deposited in the pocket 38 when the rotor 23 is in open" positionand then in its cycle of operation, the material deposited will bedumped at the "dump" position into the tray or other receptacle.

Special protective features of the improved mecha nism include theprovision of the horizontal rib I09 in the liner base wall which tiltsany paper currency off of a vertical position, when rotor 23 is in openposition, and which otherwise might have laid flat on the liner wall; sothat it falls over by gravity when the rotor 23 is in the open" positionof FIG. [3 and comes to rest on the liner bottom wall of the open pocket38.

Other safety features characterizing the mechanism of the inventioninvolve the deadlock 71 for the rotor when in "home" position. Thedeadlocking pin 71 is inaccessible from the exterior of the housing ofthe remote unit 1 and thus performs the same function as the bolt workfor safes or vault doors. Further, the noback" pawl and ratchetmechanism 103-]02 prevents the rotor from being backed away to an open"position when the gear drive is disengaged and the rotor is driven byits friction drive away from open" position.

Another safeguard characterizing the improved mechanism is the lightbeam sensor systems which effectively signal or sense the presence orabsence of objects in the pocket when in open" position. This isaccomplished in a very simple manner involving no moving parts requiringadjustment, servicing and upkeep other than electric eye bulbs orphotocells.

A further safeguard to the programmed operation 01 the rotary cashdrawer involves the sensor control plate 75, its printed circuit, itsoptical cells 78, 79 and 80, and the optical interrupting fingers 82 and84. This mechanism senses and provides limit switch control for theoperation of the rotor by sensing the arrival. of the rotor at each ofthe home," open and dump positions.

Inspection of FIGS. 2, 13, 14 and 15 indicate that at no time is athrough opening presented by the rotary cash drawer mechanism from theexterior to the interior of the unit, and that there is always a heavyprotective plate wall presented guarding the interior of the unit. Thiswall may be formed of metal of required thickness and composition topresent the necessary security against attack in accordance with banksecurity and underwriter's specifications.

WlRlNG DIAGRAM FIG. 17 is a schematic diagram for the wiring for theprogrammed operation of the rotary cash drawer 6. The wiring isillustrated typically in some of the other views of the drawings bycables, harnesses. wires, etc. In FIG. 17, several terminal strips. T-1,T-2, T-3, 8-16 and PWR-9, are shown as well as relays 107-SSR1, l07-SSR2and l07-SSR3. Each of the relays may have a number of pin connections toprovide the circuitry programmed operation.

Components illustrated, described and identified above and indicated inFIG. 17, include a transformer indicated at 106', the solenoid for therotor lock pin 71 indicated at 74; the photocell light beam switchsensors indicating the presence or absence of currency in the pocketidentified at 63 and 64', the light bulbs 60a and 60b; the frictiondrive motor 95; the gear drive motor 92; the drive plate solenoid 97;and the printed circuit board 75 carrying the rotor home" sensor 79, therotor open" sensor 78, and the rotor dump" sensor 80, which function aslimit switches. Connection for such components are indicateddiagrammatically at terminal strip 5-16, and the various power supplyconnections are shown at PWR-9.

The various components and terminals or terminal pins for the wiring,illustrated in FIG. 17, may be contained in or on the control housing108. The circuitry thus represented in FIG. 17 connects and controls thecomponents for operation of the mechanism in the manner described.

IN GENERAL Accordingly. the new currency dispenser rotary cash drawermechanism concept eliminates any drawer manipulation by a customer,presents a free, full and larger access opening for removal of currencydispensed, provides a rugged construction, easy to operate andexhibiting maximum security, provides the new dumping feature and itsadvantages described, provides a construction which does not projectoutwardly when open, thus eliminating possible injury or damage and atthe same time, protecting currency in the open pocket from windcurrents, provides a construction which is friction-driven when closingto avoid injury to the user, provides a construction wherein there is nothrough access between the exterior and the interior of the banking unitthrough the rotary cash drawer, provides a construction having maximumpocket space in a minimum volume of the cash drawer mechanism, andprovides a construction which achieves the objectives stated, eliminatesthe difficulties heretofore existing in the art which have beendescribed, and solves problems and obtains the new results indicated.
